Save the voicemails. The boring ones. “Call me back, it’s Mom” becomes treasure someday.

A voice is the detail that goes first and cannot be rebuilt from memory. You will hold on to a face for decades and still lose the exact way somebody said your name when they were in a hurry. Ordinary recordings keep that better than staged ones, because nobody performs in a fifteen second message about dinner. The boring ones turn out to be the accurate ones.

If you have a saved message from somebody you love, you might back it up somewhere a new phone cannot wipe it. That is all. No need to listen now, only to make sure it is there when you want it.
